A classic juxtaposition, familiar of course, but no less well observed. The three elements are placed within the frame with precision and the overall tonality is subtle. It's the policeman's expression that's perfect here.

The light is so strong in this photo but it's been handled well, and the shadow detail is all there. More to the point it's a fantastic street portrait and very atmospheric.

The sunlight reflecting off the dancers hat and into the lens gives this photo an unreal feel, but we're brought back to reality by the 'event staff' stewards keeping the crowd in order, a rather clever combination. It certainly illustrates the 'photo opportunity' feel of the event rather well.

This feels more personal than the other photos of the dancers in the carnival, it's more revealing of the person photographed. There's an awkwardness to it but it works.

Nicely composed, only the strong colours visible in the background intrude into the subtle tones of the costume. But with this kind of street photography what you see is often what you get.

The questioning gaze combined with an almost comic stance makes this the pick of the set, the 'heart shaped glasses' girl in the background make a perfect counterpoint; it's a really fine street portrait. Carnival is one of those events that's really hard to get original photos from, but here, with the remit of recording what he sees, the photographer has come up with some interesting images.
